There are three expressions for the surface roughness height parameter of stainless steel plates. One is the arithmetic mean deviation Ra, which refers to the arithmetic mean of the isolation values between the points on the induction line along the measurement direction (Y direction) and the reference line within the sampling length; The second type is the micro roughness ten point height Rz, which refers to the sum of the average height of five major inductive peaks and the average depth of five major inductive valleys within the sampling length; The third method is to generalize the high altitude Ry, which refers to the interval between the peak top line and the trough bottom line within the sampling length.

Nowadays, Ra is primarily used in the mechanical manufacturing industry. The Ra value is calculated according to the following formula: Ra=1/l ∫ t0 | Y (x) | dx or approximately Ra=1/n ∑ | Yi |. In the formula, Y is the interval between the point on the induction line and the reference line (centerline); Io is the sampling length.

Roughness is often used to characterize steel plates, as stainless steel plates must have some roughness before coating, otherwise the biting force of the paint will be insufficient, and over time they will easily fall off.

The common finishing processes for stainless steel plate surfaces mainly include matte, mirror finish, and colorful surface treatment, and their various applications are more suitable.
Surface matte refers to the uniform silver white color and excellent metallic luster of the processed stainless steel surface. This treatment not only achieves surface beauty, but also enhances the material's corrosion resistance. Due to the matte treatment of stainless steel plates, impurities and surface iron rich layers in the stainless steel matrix can be eliminated, and chromium and nickel can be enriched on the surface of the stainless steel plate to form an undamaged passivation film, making it have good corrosion resistance.
